To all whom z'tmay concern:

Be itknown that I, STEPHEN N. CORN- WALL, 'a citizen of the UnitedStates, and'a resident of Springfield, in the county of Greene and Stateof Missouri, have invented a new Improvementin Curbing, &c.,

ofwhich the following is a full, clear, and

r exact description.

'My invention is animprovement in curbing systems, and has for itsobject the provision of. a simple and inexpensive form construction foraiding in the laying of plastic curbing and the like which may be easilyset up and taken down, ma be used indefinitely and which will be capableof many adjustments for constructions of different size andshape.

, laid with their ends abutting. Each board In the drawings :F igure 1is a PGI'SPOC': tive view of a section of form set up; Fig. 2 is atransverse section; Fig. 3 is a perspect-ive view of a joint-1 betweentwo boards;-and Fig. 41s a perspective view of one of the frames.

In the present construction, the form is composed of a plurality ofplates or boards 1 0 suitable width, length and thickness has at one enda substantially V-shaped groove 2-extending thefull width of the end,and at the other end, the board is cut away or beveled at each side asindicated at 3, to fit the groove of the adjacent board. The boards aresup-ported at each end by means of the frame 4 shown in Fig. 4.

Each of the said frames is of rectangular form, and in.one.side athreaded opening is provided for receiving a bolt 5. A set screw 6 isthreaded through an opening in one end of each frame, the bolt and setscrew being at right-angles to each other. The frames are held to the'ends of the A boards by means of the bolt 5 which is passed throughanopening in the end of the board an'dis then threadedv into the 'frame.The head 7 of the bolt' is countersunk, as shown in Fig. 2, -and a stake8 of 'iron or the'like is driven through the frame int o =th e ground.The boards and stakes vare arranged at the proper incline to agree--tically on the stakes "tothe proper height,

'afterwhich they are held in place by clampwith the slant'of theadjacent facelof the curb, and the boards are then adjusted vering theset screws on the stakes.

,,i' "-,'-'A plura1ity of templets 9 are provided,

each having its side edges 11 and 12 inclined toward each other tocorrespond with the angles of the faces of the curbing to the vertical,-and at its upper. end each templet has a hook 10 for engaging over theedge of the boards 1. The templets are arranged at distances from eachother sufiicient' to support the boards properly against I the pressureof the plasticmaterial, and

plates or boards 13 ofless width than boards 1 are arranged on theopposite edges of the templets. The boards 13 are supported by hangers14, one of which is pivoted at one end to each templet, as indicated at15, Figs. 1 and 2. Each hanger is in the form of a bar having one endpivoted to the board as above mentioned, and provided at the oppositeend with an upwardly extending lug or stop 16. such length and soarranged with respect to the templets that there is just sufficientdistance between the innerface of lug 16 and the adjacent edge 11 of thetemplet to receive a plate 13 as shown more especially in Fig. 2.

If there isany tendency on the part of the boards 1 and -13 to springapart, or of' the boards 13 to drop down, clamps 17 may be arranged atthe templets, or at other suitable points. The clamps 17 are of usualform, and are arranged to press the board 13 toward the boards 1-.

I Then the form is set up as described, the ground is cut away thewidthof the curb plus the thickness of boards, as indicated at 18 in Fig. 2,and'the soil is cut away at the side of the cut. 18 adjacent to boards13 t0 aline with the inner face of the said boards. The plastic materialis then tamped into the form between the templets, and the top coat-isspread on. The clamps 17 are removed first, after which boards 13 may beremoved, and the face of the curbing is finished by brushing over in theusual manner.

The ends of boards 13: are connected in the same manner as are theboards1,

that is as shown in Fig. 3. The. templet 9 may be constructed to giveany desired incline to either face of the curb and to give The hangersare of 1 any desired thickness. The boards may be of wood or may bemetal plates as may also be the templets. The frames are not necessagilysquare and other means may be used to clamp them on the stakes. v
